From article: Detroit's crackdown on marijuana storefront shops could lead to about 150 fewer shops than existed in the city at the height of the industry, Mayor Mike Duggan said.

Teams of city inspectors and police officers have begun visiting stores to enforce Detroit's new medical marijuana ordinances, which took effect March 1.

"There is room in this town for probably 50 or 60 medical marijuana dispensaries spaced legitimately, and they have to be in industrial or high commercial areas," Duggan said in an interview. "They can't be in residential areas."

...Detroit has received 250 applications to open medical marijuana centers under the new ordinance, officials said. Of those, 58 were incomplete. About 112 applications are believed to be for operations in ineligible drug-free zones.
